What is backflow and why is it dangerous?

Backflow occurs when contaminated water or chemicals flow backward into your home's clean water supply instead of flowing in the proper direction. This happens when water pressure in the main supply drops or reverses. Backflow is dangerous because it contaminates your drinking water with sewage, fertilizers, pesticides, or other hazardous materials, creating serious health risks for your family. This contamination can also affect your entire neighborhood's water supply. A backflow prevention device stops this reverse flow, protecting your water quality. Syracuse requires backflow prevention for certain homes and businesses.

Do I need a backflow preventer in my home?

Whether you need a backflow preventer depends on your local plumbing code and water system. Syracuse and many municipalities now require backflow prevention devices for homes with: irrigation systems, fire suppression systems, pools or hot tubs, lawn sprinklers, boilers, or water softeners. Even if not required, installing a backflow preventer is an inexpensive investment that protects your family's health. Mr. Rooter can assess your home's plumbing and determine if a backflow prevention device is necessary or recommended for your situation.

How often do backflow prevention devices need testing?

Most municipalities, including Syracuse, require annual backflow prevention device testing. Some jurisdictions may require testing every two years depending on device type and location. Annual testing ensures your device is functioning properly and blocking contamination effectively. Neglecting required testing can result in fines and legal liability if contamination occurs. Mr. Rooter provides professional backflow prevention device testing and maintains records for compliance documentation. We schedule your tests annually so you stay compliant with local regulations.

What happens if my backflow preventer fails testing?

If your backflow prevention device fails testing, it means the device is not properly blocking contaminated water flow and needs repair or replacement immediately. A failed device puts your home's water supply at risk and violates local plumbing codes. Mr. Rooter will repair the device if possible by cleaning, adjusting, or replacing internal components. If repair isn't possible, we replace the device with a new, certified unit. You cannot use your water system until the device passes testing, so prompt repair is essential.

What's the difference between types of backflow prevention devices?

Common backflow prevention devices include: Dual Check Valves (simplest, lowest cost, good for low-hazard situations), Pressure Vacuum Breakers (for irrigation and sprinkler systems), Reduced Pressure Zone Devices (highest level of protection, required for high-hazard connections). The right device depends on your plumbing setup and local code requirements. Mr. Rooter installs the appropriate backflow prevention device for your home and ensures it meets Syracuse regulations. During annual testing, we verify your device type is correct for your application and functions properly.

Backflow is caused by a crossed connection in your plumbing which leads to either of the following conditions:
- Back pressure is when water entering your home has a lower pressure than that already in your plumbing.
- Back siphonage occurs when the pressure of water entering your home is higher than that of the water in your system.
In both cases, this pressure difference creates a siphoning effect which causes clean and contaminated water supplies to mix. This means water from toilets, shower runoff, garbage disposal waste and even pesticides with a garden hose attachment can enter your drinking water.

Backflow Prevention Devices

Most building codes specify that backflow prevention devices are installed in any areas where the potential for cross-connection exists. Some of the home appliances that commonly require backflow prevention devices include the following:

Dishwashers
Garbage Disposals
Toilets
Faucets with Hose Attachments
Pools
Lawn Irrigation Systems

Many older homes may not have proper backflow prevention devices in place. Furthermore, different hazards may require different levels of protection. If you suspect your home does not have proper prevention devices in place, contact Mr. Rooter Plumbing today — often the effects of backflow may not be noticeable on a day-to-day basis, but can cause serious health problems over time.
